Red-tailed Hawk 133 



Red-tailed Hawk. — Buteo borealis. 20.00 



Uncommon Permanent Resident 



Field marks. — Tail bright reddish, with one narrow band near 

 the tip; under parts white, streaked with brown; upper 

 parts dark brown. 



The habits of this Hawk are almost identical with those 

 of the Red-shoulder, but it comes out in the open less and is 

 fond of the wilder, wooded sections of the County. Its nest 

 and eggs are similar to those of the preceding species. 



American Goshawk. — Accipiter airkapillus. 22.00 



Irregular Winter Visitant 



Field marks. — Upper parts slaty gray and under parts lighter; 

 entire bird appears barred and streaked with darker gray. 



Some Winters a number have been seen here; again, some 

 years, it appears to be absent. 



Cooper's Hawk. — Accipiter cooperii. 15.54 



Uncommon Summer Resident 



Field marks. — Tail rounded, with V shaped bars; upper parts 

 dark gray; under parts light, barred with brown. 



This is considered about the most destructive to poultry of 

 all the Hawks. It nests in trees, laying from four to six bluish- 

 white eggs.
